If you need a place to get a Fresnel lense magnifier online, REI has them. On water purification I exclusively use the Katadyn's Micropur MP1 (or boiling of course) for my water purification needs when hiking and for my car kits as well as my EDC. About every other weekend I go on a long hike in extremely hot weather (this time of year) where carrying the amount of water I need is simply not possible. I have had great success with the Katadyn's Micropur MP1 tabs. I have had to use them on some very questionable water and have yet to get sick (knocking on wood). What I do in when hiking to avoid the long wait time associated with the Katadyn's Micropur MP1 tabs is use them in conjunction with an (chemical-free) activated charcol filter water bottle. The filter immediatly removes the bacteria-based nasties and then the Katadyn's Micropur MP1 tabs are left only with the job of killing the viruses, which they do rather quickly. The way I understand it they only take about 15 min to kill viruses. I give it 30 min just to be safe <img src="/images/graemlins/laugh.gif" alt="" />. I keep one of these bottle filters in my car kit as well. For EDC I only carry the tabs (6 of them). Another side note on the Katadyn's Micropur MP1 tabs... I have had success cutting them in half right through the foil packaging (requires a razor sharp blade) with out having them come in contact with my skin. This is handy when I only have smaller containers to work with. I know you can use the tabs with less than a liter of water but I can't see any reason to injest more chemicals than is necessary in any situation. <img src="/images/graemlins/smile.gif" alt="" />

Brian,
In North america its not generally viruses you have to worry about but rather bacteria and protozoa. The water temps in this part of the world does not support virus growth. I would wait the full 3-4 hrs before consuming as its the bacteria and protozoa you are wanting to kill and it takes longer for them.
My opinion of course.

Bacteria, Virii and other nasties can be interesting to live thorugh... Having been in Milwaukee several years ago during a certian Crypto outbreak...
One of my packs has a sealed fish tank filter and AquaPur in a gallon zippy bag. I use the fish filter to strain the gross(as in big bits) out of the water, the charchol gets some chemicals and the rest gets taken kare of with either boiling or the aquapure.
It actually works! One of the two times I used it, I was at a campsite that had signs that the water was not potable out of the pump for one and used a pot to boil things after straining. The other time, it was a rainy day and we realised that some dork haddn't dug a hole and that the pond was not as clean as we thought. I think it was a mental tummy ache after that one...

There is a pass around copy of Cody's book in the Lending Library. There are a few scattered comments from the readers there. http://www.equipped.org/ubbthreads/showf...amp;amp;fpart=1

You can go to any Staples or Office Depot and find a thin plastic 8.5x11 sheet of magnifying plastic for reading. Look for it in the magnifying glasses and office tools section. It costs about $7-9 and can be cut to any size. [color:"red"] I outfitted 6 kits with one sheet and made different sized lenses. [/color] -----------------------------------------------------
Flipper , you may want to try those lenses out before you take a chance on them its my understanding that for the lens to work right it needs to have the concentric rings of the center a lens not cut out from the center of the larger sheet wont focus properly Regards Yukon

You are correct.
The center piece works best but because they are flexible I stated fire with all of them by slightly bending them to focus the beam correctly.
Just takes some practice.

First, I think it's a great book. Partly because it's a book, and partly because he simply seems to want to hammer the core body temp point into your head, he goes into great depth on what goes wrong when you're "out there", how it goes wrong and why it goes wrong. That shows up on this site, but it's not delved into as deeply. Take matches for instance, Lundin describes how hard it can be to operate a match in freezing cold weather with your gloves off. I tended to carry matches in all my kits, but not flint starters which are much easier to use when your hands are basically frozen. The same message comes from here and Lundin's book (and other books), but it was Lundin's description that finally made it seem important to me to have multiple dissimilar methods of fire creation. I think my point is that I learned a lot on this site, and I learned a lot from his book. Having multiple sources fills in gaps that one source would have.
Also, I think Lundin's book is written to a very different audience. As a backpacker, I felt some of his kit ideas were a lot more applicable to me than something coming from a pilot. Pilots may think they are weight-conscious about gear, but backpackers turn it into entertainment, going through each others gear to point out where they could shave half an ounce. You take a different view of things when you're going to schlep it on your person for 5 double digit mile days in a row than when you're stowing it in a plane. I'm going out into the wilderness on purpose, not ending up there by accident. On the other hand I think a lot of backpackers (due to the gear-weight mania) neglect backups of important items.
I think the cost-consciousness has a benefit. ETS tends to the high-end, and Lundin's book tends to the low-end. Somewhere in the middle lies the path most of us will take. The benefit of the cost-conscious version is that for a few bucks you can have pretty much what you need, and then fill it in over time with more expensive stuff when the first stuff wears out or you decided to make another kit for another purpose, rather than spending a bunch and still feeling like you aren't quite prepared. Like you've never had a kit "accident" that ruined something inside? <img src="/images/graemlins/smile.gif" alt="" />
This might be horrifying to some, but on recent backpacking trips I ended up delving into the emergency kits for some day-to-day stuff. Stuff that either wasn't used up in the process, or that I had backups of backups of. The iodine bottle was one such item. One day we "slack-packed" (someone drives your heavy pack from trailhead-to-trailhead and you walk with a lighter set of essentials). We carry a filter with us every time we hike, but since I was slacking with a fanny pack in early April, I didn't have room for such a bulky item. Having a backup of tincture of iodine allowed me to leave the filter, but still be able to treat water inexpensively and practically. Opening the iodine tablets carries that risk they'll get damp and useless, but the liquid tincture is pretty much made for repeated opening and use. And completely off-topic, we made lunch for the day, but left it in the hostel fridge. Oops. We were prepared enough with other snacks, Clif bars etc that we were kind of comfortable even without lunch. My wife used to think I was a bit nuts with all the preparedness, that's until little things go wrong and we rely on what I've made sure we have with us. Nothing makes you look like you're not a nutcase than actual stuff going wrong. Even if it's just not going without lunch until you hit the trailhead and can grab some dinner.

Nutcase? Who? <img src="/images/graemlins/smile.gif" alt="" /> My personal kits have always been...well... personal and usually directly integrated in to everyday EDC, spread out over pockets, etc so it appears to the PHRASECENSOREDPOSTERSHOULDKNOWBETTER. (and even my wife) that rather than being prepared for disaster, I'm jus a guy carrying a lot of gadgets (although the ferocerium rod is a bit hard to explain <img src="/images/graemlins/ooo.gif" alt="" />). Anyway, I remeber when I first put together and started carrying a large backpack-sized kit in my car and my wife's car she (although she didnt come right out and say it) thought I might be a bit of a nutcase. Ah but those days are long gone. Whether it's baby diapers, a screwdriver on her SOG paratool or the allergy meds in the FAK, she LOVES our car kits now. Any time she uses even the smallest item from the kit she lets me know so I can restock it or she restocks it herself. I have even caught her adding little useful things to the kit in her car. <img src="/images/graemlins/smile.gif" alt="" />

Yeah, my PSK is pretty much just a very comprehensive, things gone wrong oriented, EDC. I have no compunction about raiding it on a daily basis as long as it gets restocked. There is the miniscule chance of things not being present when needed but I feel that my better familiartity with the stuff I carry more than offsets this. I realise that this is purely personal preference though and probably slao stems from coming at emergency preparedness from the backpacking point of view/background rather than something like a pilot.
